January 2017Does Competition Affect Bank Risk?
with Ross Levine, Chen Lin: w23080
Although policymakers often discuss tradeoffs between bank competition and stability, past research provides differing theoretical perspectives and empirical results on the impact of competition on risk. In this paper, we employ a new approach for identifying exogenous changes in the competitive pressures facing individual banks and discover that an intensification of competition materially boosts bank risk. With respect to the mechanisms, we find that competition reduces bank profits, charter values, and relationship lending and increases banks’ provision of nontraditional banking services.
